PopCrush has been hosting one of the most popular versus competitions between known K-pop groups. Now, the girl groups, f(x) and Apink are the one who gets to face each other.

The semi-final round for the PopCrush search for the best K-pop group has just succeeded and it had garnered more than 20 million votes. Now, it's time for the competition to proceed to the final round, leaving only f(x) and Apink to battle it out for supremacy.

F(x), after beating Girls' Generation, went on to proceed to the final round. According to Pop Crush, f(x) had garnered 50.62% of the total votes, thereby making it eligible to proceed to the final round.

On the other hand, here's Apink who took over SISTAR as it got a whopping 90.69% of the votes. Obviously, Apink has the clear advantage against f(x) when it comes to the vote percentages.

However, the final round is more than just settling on the previous round's statistics. Apink are considered to be veterans in the K-pop world, as they debuted way back in 2011.

Their latest release is "December's Dear" which includes three duet songs that all proved to be chart toppers. It's lead track, "'Cause You're My Star", also helped them achieve greater popularity.

Meanwhile, here comes f(x) who is best known to have electro-themed kind of music. However, they have a slight advantage against Apink when it comes to experience as they debuted in 2009, two years before Apink. Since 2011, the girl group had released four full-length albums.

F(x) is also expected to have a comeback sometimes this year, after its recent "4 Walls / Cowboy" was met with massive success upon its release in Japan last year. Whichever the case is, the voting between the two will be a tight competition. Voting will end on March 31.
